Nov 1 morning - clouds moving by very fast, breezy as winds are not making it to the surface yet. Comments by Upton.
75 TO 85 KT LLJ AT 3000 FEET REACHES THE REGION AHEAD OF THE BAND
OF LOW TOPPED CONVECTION...AT LEAST PER THE 06Z RAP. BASED ON
WHAT`S HAPPENING OUT WEST...STABILITY IS FORTUNATELY PREVENTING
THE LLJ FROM REACHING THE SURFACE. BASED ON THE RAP
SOUNDINGS...THIS SHOULD BE THE CASE HERE TOO.
IT`S NOT UNTIL THE LOW TOPPED CONVECTION REACHES THE REGION THAT
MOMENTUM TRANSFERRED TO THE SURFACE IS OCCURRING. THERE IS STILL
A SIGNIFICANT LLJ THAT WINDS SHOULD APPROACH 50 KT. SINCE
CONFIDENCE FOR EXCEEDING 50 KT IS NOT HIGH ENOUGH...WILL KEEP US
AT WIND ADVISORY LEVELS. ALSO...GRID FORECAST IS NOT ACCOUNTING
FOR THE PEAK GUSTS.
WILL NEED TO WATCH THIS DEVELOPING SITUATION CLOSELY THE NEXT 6
HOURS. THERE IS POTENTIAL HERE FOR A SIGNIFICANT WIND EVENT. SPC
HAS BEEN ISSUING WATCHES FOR THIS OUT WEST AND SINCE THIS IS CONVECTIVE
NWS WILL USE CONVECTIVE PRODUCTS (I.E. SVR) EVEN THOUGH THERE
IS NO THUNDER.
